Abstract
Porcine circovirus 3 (PCV3) is a newly emerged circovirus
discovered in 2016, and since then is threatening the swine industry
worldwide. In this study, we evaluated the presence of different PCV3
strains in swine herds from Brazil. PCV3 was detected by qPCR in
different samples from different life stages. Sequencing was performed
with seventeen positive samples. This study reported the coinfection of
different PCV3 strains in one animal. This study provides insights into
the genetic diversity of PCV3 strains circulating in the Brazilian swine
herds.
